Re: [ptp-dev] Questions about widgets in JAXB plugin

["Albert L. Rossi" <arossi@xxxxxxxxxxxxx>]

Dave,

a few random thoughts before I go out.  Would it be sufficient to give a widget something like this:

<enabled-if>(widgetA#enabled && widgetB#enabled) | !widgetC#selected</enabled-if>
<visible-if>widgetA#visible && widgetB#visible</visible-if>

The changes I'd have to make:

1.  give all widgets an id that is visible in the configuration
2.  map the widgets to their ids
3.  write a parser for the contents
4.  maintain for each widget a validator for each of its boolean properties (visible, enabled, selected ...) and run it on each update.

Am I missing something, offhand?

This, as you can see, is not a trivial change, but I'm sure I can make it work.
